The recent OSS stuff is working pretty good. I have one area, where one sound clip stops and the next starts, that sometimes has problems. Sometimes the second clip runs normally, and sometimes there is just a brief bit of the very beginning of the second clip.
I think this is where the problem is. The difference I see is that when it breaks, some wodNotifyClient msgs are received before the wodGetPosition messages are set to valid values for the new clip. When it works, those values get set before the wodNotifyClient msgs. Then again, I really don't understand what is going on.
A trace from when it fails:

It continues this way until the DSP buffer is empty, and nothing further is written to it.
